Abstract (en)

[origin: WO2022240716A2] A III-nitride based device is fabricated having an in-plane lattice constant or strain that is more than 30% biaxially relaxed, by creating a III-nitride based decomposition stop layer on or above a III-nitride based decomposition layer, wherein a temperature is increased to decompose the III-nitride based decomposition layer; and growing a III-nitride based device structure on or above the III-nitride based decomposition stop layer. The III-nitride based device structure includes at least one of an n-type layer, active layer, and p-type layer, and at least one of the n-type layer, active layer and p-type layer has an in-plane lattice constant or strain that is preferably more than 30% biaxially relaxed, more preferably 50% or more biaxially relaxed, and most preferably at least 70% biaxially relaxed.
